ABSTRACT:
A laser device for generating high input power by minimization of surface flection losses between adjacent elements of the device. A laser medium having an index of refraction substantially greater than 1.5 is fluid cooled in a sealed tube by an optically clear cooling medium having a substantially lower refractive index. The indices of the laser and cooling mediums are matched to each other by thin film coatings of index matching material attached to the laser medium, each coating having a thickness of one quarter of the lasing wavelength.
